and this goes back to the age-old argument of what pH does this fish like and what does that fish like.
unless youre keeping fish in something extremely acid or extremely alkaline, they will most likely adapt. breed? maybe not. live and live nicely? quite well.
ct-death is right, not ALL fish can adapt to a wide range of pH, but MOST can. some people will tell you that a fish will live a 'happier' and more 'robust' lifestyle in a tank with a pH that matches their native surroundings.. let me tell you, i have never EVER messed with the pH of any of my tanks, ever, (let me repeat myself, EVER..) and the only losses i have ever had were due to initial acclimation, and natural cause deaths (ie. age). were my fish 'happy'? that i couldnt tell you... but they never jumped out of the open-lid tanks they were in, and they ate well, and they were lively.. thats the closest thing i could see to them being 'happy'.
i wouldnt change your pH, it's probably just fine.
